METAL CATTLE-GUARD.

Application filed May 6, 1914.

To all whom it may concern Be it known that I, EUGENE Coon, a citizen of the United States, residing at Niles, county of Berrien, State of Michigan, have invented certain new and useful Improvements in Metal Cattle-Guards, of which the following is a specification.

This invention relates to improvements in metal cattle guards.

The main objects of this invention are: First, to provide an improved metal cattle guard unit which, when in position in the road bed, is open for free circulation of the air and one in which there is a relatively small amount of metal contacting with the ties by which it is supported. Second, to provide an improved metal cattle guard unit in which the teeth have the effect and appearance of being long without the weakness of long teeth, and one which is economical in the matter of material.

Further objects, and objects relating to structural details, Will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing forming a part of this specification, in which Figure I is a detail perspective view of one of my improved cattle guard units. Fig. II is a detail plan view of the channel-iron blank, with the teeth which are struck up from the web of the channel-iron indicated therein.

In the drawing similar reference numerals refer to similar parts in both views.

Referring to the drawing, the unit designated generally by the numeral 1, is formed of channel-iron or suitable plate metal rolled into channel shape. The body has a double series of A-shaped teeth 2 struck laterally and oppositely from the web thereof and disposed in planes in close proximity to and parallel with the planes of the flanges or legs 4 of the body. The teeth of the series are alternately disposed, the point of one tooth being struck from between the bases of the opposite adjacent teeth. The length of the teeth corresponds to the width of the body. The teeth are uniformly spaced, thus providing the diagonal tie members 5 between the teeth. These tie Specification of Letters Patent.

members are comparatively narrow so that a comparatively large number of teeth are provided and so that the unit is open for the free circulation of the air.

In use, the units are laid transversely of the ties and secured by spikes, holes 6 being provided at each end for the spikes. Only the edges of the flanges contact with the ties, the main body of the guard being spaced above the tie so that, as stated, a free circulation of air is permitted.

The teeth being close to the flange have the appearance and efiect of being of the length of the teeth plus the height of the flange. This gives the efiect and appearance of long teeth without the weakness which would result from such teeth and without necessitating the use of wide bars.

The units may be placed on the ties as circumstances may render advisable. The units are entirely independent from each other, and in the event of a dragging part on a car, it is likely that only a single unit will be disturbed or torn from the road bed, not only lessening the damage to the guard, but also lessening the liability of derailment of the train. The guard units are simple and economical to produce.

I have illustrated my improved guard unit in the particular form in which I have embodied the same for the market and which I find to be highly satisfactory. Certain modifications and adaptations for particular uses will suggest themselves to those skilled in the art to which this invention relates.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A cattle guard unit consisting of a downwardly facing channel-shaped body having a series of integral A-shaped teeth at each edge struck laterally and oppositely from the web of the body and disposed in planes parallel with and in close proximity to the planes of the flanges of the body, the teeth of the series being alternately disposed and uniformly spaced longitudinally of the body, there being a series of narrow diagonally disposed tie members between the teeth, the point of one tooth being struck from between the bases of the opposed adjacent pair of teeth, the length of the teeth being approximately the width of the web of the body.

2. A cattle guard unit consisting of a downwardly facing channel-shaped body having a series of integral A-shaped teeth at each edge struck laterally and oppositely body, there being a series of narrow diagonally disposed tie members between the teeth.

3.A cattle guard unit consisting of a downwardly facing channel-shaped" body having a series of integral A-shaped teeth at each edge struck laterally and oppositely from the Web of the body and disposed in planes parallel with andin close proximity to the planes of the flanges of the body, the teeth of the series being alternately disposed, there being a series of narrow diagonally disposed tie members between the teeth. 41' A cattle guard unit consisting of a Copies of this patent may be obtained for channel-iron body disposed face downwardly and having series of A-shaped teeth disposed in planes parallel with the planes of the flanges 'ofthe body, the teeth of the series being alternately disposed, alternating teeth being struck oppositely from the Web of the body.

5. A cattle guard unit consisting of a channel-iron body disposed face (lOWIl- Wardly and having a series of A-shaped teeth at each edge, the teeth of the series being alternately disposed, alternate teeth being strucleoppositel'y from the Web of the body. a In Witness whereof, I havehereunto set my hand-and seal in the presence of two Witnesses.
